Flange Insert 17mm Compatible with S9/S12 Wearable Breast Pump, Original Part Accessories Replacement, Reduce 24mm Nipple Tunnel Down to 17mm, Correct Size More Comfortable, Pump Parts Replace 4 PCS

Has all the types for wearable pumps. It would help if there were two each.

Dug up my pump after not using for the past year for my 2nd child, and was distressed to find there was no suction. Used these to replace my duck bills and it now works like new. I use these with my spectra caracups and they fit perfectly and suction is great!

Works perfect with the pumps as if they were name brand.

Fit perfectly

I bought this to make life easier with pumping. Being tied to a wall every few hours while working full time, a toddler and endless cleaning tasks I knew I wouldn’t be able keep my supply up if I relied on my spectra (though great). I was skeptical because of the price and only hearing about famous brands like the Willow or the Elvie. Well Im impressed. It is loud and bulky so not descreet at work but I can continue to work and not sign out to pump. Im in the medical field so my scrubs cover it up a bit. If you put the parts together correctly the suction is good and the output is good. I’ve had times where I rushed putting it on and after 20 so minutes I see barely anything has come out. Im not an overproducer at all but I can get 2-3 oz every 2-3 hrs. It is easy to clean. The pump comes with an extra duckbill which is great, a 19mm insert,charger and a carry bag. I pump atleast 30 minutes 3x at work and I charge it after that but it’s not dead. I’ve been using this about 2months sometimes pumping 5-6x a day. Im very impressed with it.

If you are looking for a valve to fit the original momcozy s12 this is it!!I kept getting sent the valve for the s12 pro(from but the manufacturer and on Amazon) and it did not fit. Way too short.But this one definitely fits the original s12(not the pros!!!). It’s the longer valve. People says it touches but it does not touch the container. It’s the same as the original. It fits like the valve that originally came with the s12. I’m one happy customer finally!!

It didn’t work with my S9 pump, I thought something was wrong with my wearable pump because of this product, suction was 0. I almost bought another wearable pump, put the old parts together again and it worked. Now we can’t return this and $16 went to the garbage, DONT WASTE YOUR MONEY ON THIS PRODUCT.

I have the spectra caracups and this is a great replacement dupe for the spectra duckbills. Spectra duckbills are 14.99 for one pair and these are 9.99 for 3 pair. It does the job but honestly if you are an exclusive pumper they will not last long as I replace them every two weeks or so as I feel it’s losing suction.Update: I am not sure what’s happening but last few times trying to order the 6 pack of duckbills I keep receiving a pair of duckbills and a diaphragm. I am unsure if the company mislabeled their products or amazon workers are clueless. This has caused me to stop purchasing entirely bc I do not want the risk of getting the wrong item.
